This invention relates more particularl to an improved type of sundaedish blan feeding mechanism, and is adivision of my co pendingapplication for patent for a ,multiple automatic folding machine. filedSeptember th, 1921, Serial Number 499,- t 614:.'

'5Itis an object of this invention to provide 1 a .dish forming machinewith an improved .10 attachment operable; from the machine andadapted'to automatically feed sundae dish blanks into the machine one ata time to be formed, into sundae dishes.

It is also an object of the invention to 16. provide a dish formingmachine with .a blank feeding mechanism operable by a mutilated gearmechanism for removing prepared blanks singly from a blank holdingmagazine. 7 i t is a further object of this invention to provide aforming machine with a blank feed mechanism including a magazine andintermittently operated means for removing blanks from the magazine oneat a time by a slight buckling movement.

It is furthermore an object of the invention to provide a blank feedinmechanism for a dish forming machine, sai mechanism having a manuallyadjustable clutch means for timing the feedin mechanism.

It is an important 0 ject of this invention to provide a dish formingmachine with a blank feeding attachment of improved and simplifiedconstruction adapted tobe properly timed to buckle and remove blanks oneat a time from a magazine and feed the same into the field of operationof the forming mechanisms of the machine.

Other and further important objects of this invention will be apparentfrom the disclosures in the specification and the accompanying drawings.

The invention, in a preferred form, is illustrated in the drawings andhereinafter more fully described.

On the drawings:

Figure 1 is a top dish forming machlne equipped 'with a blank feedingmechanism embodying the principles of this invention.

Figure 2 is an-enlarged front elevation of the blank feeding mechanism.

Figure 3 is a reduced view taken on line 3 3 of'Figure 2.

Figure 4 is a sectional view taken on line 4-4 of Figure 3.

As shown on the drawings:

The reference numeral 1 indicates a pulley adapted to be driven by anyconvenient source of power to cause operation of the machine. The pulleyis mounted .to rotate on a shaft supported on the machine frame 2 and isadapted to transmit a drive through suitable gearing to a gear 3 whichdrives a shaft 4 through a clutch mechanism 5. A gear on the shaft 4 -tothe inside of the frame 2 meshes with a gear 6 to cause operation of adisk 7 connected to operate :1 Geneva gear 8. The Geneva gear 8 ismounted to operate the meshing gears 9 and 10 and thus transmits a driveto a shaft 11 which is connected by beveled gears 12 and '13 to operatethe dish forming mechanism denoted as a whole by the reference numeral14.

Mounted on the shaft 4 is a beveled gear 15 which meshes with a beveledgear 16 mounted on a shaft 17 which drives the feedlng means whichdelivers the blanks to the forming mechanism. As shown in Figure 3 theshaft 17 extends to the forward part of the machine through a bearingsleeve 18 mounted on the front plate or bracket member 19 of themachine. on the outer end of the shaft 17 is a pinion 20 in mesh with agear 21. The gear 21 in turn drives a smaller gear 22 mounted on ashaft, 23. Adjustably mounted on "the outer end of the shaft 23 is apair of mutilated gears 24 and 25 adapted to cooperate with twocorresponding mutilated gears26 and 27 res ectively which drive theblank feeding rol ers. An adjustable clutch member 30 is provided on theshaft 23 which is operated by a knurled knob 31 so that the relativeposition of the mutilated gears 24 and 25 ma be adjusted as desired withrespect to t eir respecti e feed roller gears 26 and 27. .Each feedroller com rises a plurality of disks 28 separated y diaplan view of asundae,

metric ribs 29 having two diagonally opposite corners projectingslightly be ond the periphery of the dISkS 28. The ri s 29 are coveredwith friction strips 32 made of rubber or other suitable material. Thefriction portions extend around only a portion of the periphery of therollers so as to operate upon paperblanks which are to be Keyed fed onlyat predetermined times-to theform:- in mechanism of the machine.

ounted above the blank feed rollers is a magazlne comprising a circularbase sec- P1011 33 provided with uprights 34 for hold ing a.plurality'of superimposed prepared dish blanks 35'. Keyed upon the shaft17' ad acent the bevel gear 16 is a sprocket Wheel 36 having a chain 37thereon which drlves a corresponding sprocket wheel 38 keyed to a shaft39 on the inner end of which is mounted-a driving gear 40. The drivinggear 40 is in mesh with a corresponding gear 41 which in turn drives asimilar gear 42 connected to. auxiliary advancing rollers 43 and 44 forthe paper blanks. The upper auxiliary roller 44 is inovabl'y supported,being positioned in pivoted bearing members 45 which are held in loweredposition by means of coiled springs 46 as best shown in Figure 2. Theupper ends of the springs 46 are attached to the ends of a rod 58connecting the pivoted members 45. The lower ends of the springs 46 aresecured to the machine frame. A cam 47 is mounted on the shaft 23(Figure 4) and is adapted to cooperate with a lever 48 pivoted at 49 ona bracket secured to the machine frame. A roller 50 is supported on oneend of the lever 48 and rolls on the periphery of the cam 47. Theopposite end of the lever 48 is pivoted to a short link 51 connected inturn to a bellcrank lever 52 which is pivotally mounted. on the frame ofthe machine by being keyed- .to a shaft 53. The upper end of thebellcrank leven 52 is formed in the shape of a finger 54 adapted tooperate as a pusher member. on the other end of the shaft 53 to properlyadvance the prepared paper blank toward the forming mechanism after ithas been fed forwardly by the feeding means described. The pusherfingers 54 are operated simultaneously b the rotation of the shaft v53;which: exten s across the machine in suitable brackets 55 providedtherefor begeatha'54feed' table 56. glhe ends of the ngers v projectupwar throu h slits 57 provided in the-table 56 g The operation is asfollows:

The machine is set in operation by the revolution ofthepulley 1 drivenfrom any suitable source of power. The clutch 5 is then actuated onsetto cause the drive from the pulley 1 to be transmitted to the dishforming mechanism 14 and the dish blank feeding mechanism of thisinvention. The shaft 4; is driven through the clutch connection and withit the bevel gear 15 is rotated to revolve the bevel the feedingmechanism Whic serves to continuously deliver prepared dishblanks 35tothe forming device.

The delivery of the blanks is "accom- A duplicate finger 54 is providedear'16' to drive eona plished :by means of the feed rollers having therubber friction strips or pads 32 on the portions 29 and actuated by themutilated gears 24 and 25 cooperating with the mutilated gears 26 and 27which drive the feed rollers 28. It will be seen that if the first feedroller, at the left of Figure 4, is rota-ted slightly in advance of thesecond feed roller that the lowermost blank 35 1n the magazine 33 willbe slightly buckled on account of the earlier movement of the frictionmembers 32 on the first feed roller.

The lowermost blank is thus separated from p the remaining blanks in themagazine. The blank having been properly separated or buckled, the twofeed rollers 28 are rotated in unison by means of their operatlngmutilated gears 26 and 27 and act to feed the blank forward out of themagazine the auxiliary feed rolls 43 and 44 wh1ch 1f desired, may beslightly separated at this time by means of a cam action (not shown).The auxiliary rolls 43 and 44 are normally held in oo-acting position bymeans of the coiled springs 46. The auxiliary feed rolls 43 and 44 aredriven by means of the chain 37 on the sprocket wheels 36 and 38cooperating with the gears '40, 41 and 42, and feed the blank forwardlyover. the top of the table 56. At the same time the cam 47 has acted toretract the pusher fingers 54 in the table slots 57 and after the blankhas been pushed forwardv suiiiciently by means of the auxiliary rolls 43and 44 the pusher fingers 54 are actuated by the cam 47 to push theadvanced blank forwardly a slight additional distance into properposition on the table 56 in the field of operation of the dish formingmechanism .14 to be formed into a sundae dish.
